Join us for this PSI seminar with guest speaker Dr. Hannah Stern. Optically addressable spins in materials are important platforms for quantum technologies, such as repeaters for quantum networks and quantum sensors. Identification of such systems in two-dimensional (2d) layered materials offers advantages over their bulk counterparts, as their reduced dimensionality enables more feasible on-chip integration into devices. In this talk, Dr Stern will introduce a two-dimensional material that hosts bright single photon emitting defects: hexagonal Boron Nitride (hBN). Dr. Stern will show our recent results of room-temperature optically detected magnetic resonance (ODMR) from single atomic defects in hBN, and most recent results of coherent spin control of these defects. These results represent the first identification of room-temperature ODMR and coherent control for single defects in a van der Waals material and offers a promising route towards realising a room-temperature spinphoton interface for future quantum technologies.
